Abstract - An electromagnetic energy harvester is
arrangement of harness the irrational energy from the
railroad track. When train passing on the track the irrational
energy is produced and this energy is in the form of the low
amount of power i. e., which energy is in mill watts quantity.
And energy harvester is produced the more power from the
irrational energy suitable for higher applicable railroad
appliances like warning signals, switches, and health
monitoring sensors, which has ability to consumes the power
supply up to 10 watt or more. This paper is focused on the
wasted irrational energy on the track is utilized by using the
energy harvesters into the regulated unidirectionalrotational
motion. With the significance of improved reliability,
efficiency, and quality of output power in the form of the DC
power. It has more advantages like regulates the constant
alternator RPM, and incessantly DC power supply.
Key Words: Railway track, energy harvesters, irrational
energy, applied force
1. INTRODUCTION
In today’s fast moving world energy demands&use
is even increasing to cope up with these even increasing
energy demands our need to derives various mechanism
those are capable to generate electricity. We well know that,
Energy is an essential issue, and play an important role in
our day to day life. According to law of conservation of
energy, energy can neither created nor bedestroyed,butcan
convert the energy is one form to another form. So, we can
utilize the irrational energy from the railroad track when
train is passing on that subway. Energy Harvesting is the
process that captures the small amountofenergythatwould
otherwise natural sources as well as human made sources.
The energy demand is increasing day by day and hence new
efficient energy resources need to be employed.
The energy harvesting is concentrated on the low
power applications. Such as, electronics devices cell phones,
etc. Energy can also be harvested to power small
autonomous sensors such as, those developed using MEMS
technologies these systems areoftenverysmall andrequires
little power, but their applicationsarelimitedbythereliance
on battery power. Scavenging energy from ambient
vibrations, wind, heat or light could enable smart sensors to
be functional indefinitely. Several academic andcommercial
groups have been involved in the analysis and development
of vibrations powered energy harvesting technology,
including the control and power group and optical and
semiconductor devices group at Imperial Collage London,
IMEC and the partnering Holistcenter,Adoptiveenergy,LLC,
ARVENY, MIT Boston, Victoria University of Wellington,
Georgia Tech, UC Berkeley, South Amp ton university,. The
National science foundation’s also supports an industry co
operative research center led by Virginia Tech and the
University of Texas at Dallas called the center for energy
harvesting materialsandthe systems. Currentinterestinlow
power energy harvesting is for independent sensors
networks. In these applicationsanenergyharvestingscheme
puts power stores into a capacitors then boosted toa second
storage capacitor or battery for use in the micro processors.
The power is usually used in sensors applications
and the data stored or is transmitted possibly through
wireless methods. The electromagnetic vibrations energy
harvesting system havingcontentsofmechanical conversion
elements like rack and pinions, balls screw or hydraulic
piston, mechanical magnifications systems, rotational
electromagnetic generators, electrical rectifier ,power
rectifiers and energy storage elements. The railway track
electricity generator is specially planned to design and
fabricate the conversion unit for utilizing the available
unconventional energy source.
That is tremendously available energy in low
intensity with ample quantity can be utilized. This machine
converts reciprocating motion in to rotary motion. The
rotational power is stored in flywheel & flywheel rotate
alternator that generate electricity. Railway track electricity
generation as such is not a new concept. There were many
attempts in the past using pneumatics, piezoelectric
materials, etc. but all of them proved very costly and were
not practically feasible in day-to-day real life .The persons,
which are climbing or getting down the staircase are
applying the impact force or thrustonthespringloadedstair
case steps.
This impact pressure energy can be utilized to
operate the energy flywheel through uni-directional ratchet
arrangement using chain and sprocket wheel drive. The
flywheel, which stores the energy and utilizes it for
continuous rotation of the generator operating pulley and
belt transmission system. It is best use of non conventional
source of energy, saving of coal and water for generating
electricity, eco friendly, simple mechanism, easy for
installation, easy for maintenance. It can be used on railway
station, airports, shopping mall, jogging parks.

3. WORKING PRINCIPLE
The railway track electricity generator is specially
planned to design and fabricate the conversion unit for
utilizing the available unconventional energy source. In
today’s fast moving world energy demands & use is even
increasing to cope up with these even increasing energy
demands our need to derives various mechanism those are
capable to generate electricity . That is tremendously
available energy in low intensity with ample quantity can be
utilized. This machine converts reciprocating motion in to

flywheel rotate alternator that generate electricity. Railway
track electricity generation as such is not a new concept.
There were many attempts in the past using pneumatics,
electromechanical materials etc. but all of them proved very
costly and were not practically feasible in day-to-day real
life.
4. ARRANGMENT
Fig. 2: Arrangement Of Component
This arrangement is placed below therailwaytrack.
When train is passing on the track then there minute
displacement will occur and due to that displacement and
the position of the rack goes downward and pinion will
rotate. Firstly the motion of the rack and pinion is
reciprocating in nature and then this rotation is converted
into the linear or rotary motion with the help of spur gear.
The rack and pinion and large sprocket mounted on the
same shaft i.e., shaft 1. When pinion will move then the
sprockets will also rotate andthissprocketwill beconnected
to the second shaft with the help of chain drive. Small
sprocket, flywheel, large and small gear as well as generator
are mounted on the second shaft.Whenthefirstshaftrotated
then automatically second shaft will also be rotated due to
the chain drive. Flywheel which is connected to the second
shaft is also rotated and maintained constant speed, and
flywheel will stores the kinetic energy. This kinetic energy
will be given to the generator through large and small gear
and this energy finally converted into electrical energy by
generator.
5. EXPERIMENTAL RESULT
Railway track of good quality have a track
displacement of around 0.25 inch for a moderately loaded
passing train. A sinusoidal input at 1 hz and 0.25 inch
amplitude is applied to the rack. Voltages reduced for
different power resistors are almost the same.
The time vs. time is plotted for the same 0.25 inch
sinusoidal displacement input in following fig. the initial
impact force in the first cycle is much larger than the force
required in the later cycles. Once the flywheel reaches a
certain rotational speed, the inertia of the flywheel will help

to reduce the forces required to continually run the
harvesters.

displacement at frequency 1Hz for various resistors.
6. RESULT DISCUSSIONS
The results are depending upon the working of the
flywheel speed regulations. From above observation the
voltage never reaches zero value. For the 1.0 Hzsimulations,
the generator consistently outputs 2 to 4 volts. And below
the 1.0 Hz simulations the generator output drops as 1 volt.
Whenever the initial load for harvesters running
cycle is large, and then results will be shows that load to run
continual cycles smoothers. Thisimprovementisessential in
increasing the harvesters’ reliability and wear resistance.
The initial load is due to flywheel rotation inertia will being
constant, which can be addressed in thefuturesbydesigning
a flywheel with speed dependent variable inertia.
7. CONCLUSION
This paper result is that the conversion of
bidirectional vibrations into unidirectional rotations of the
generator will reduce the backlash impact and enable
electrical generator to operate at more efficient speed.
Integration of a flywheel into the vibration harvester will
reduced the impact forces of pulse like loading, for
productions of a continuous DC output will make the power
produced by the harvesters more readily converted into
useful forms.
